I have some Jostaberry bushes. They are fairly new so I expect a proper harvest from them next year. Ken Muir says they are vigorous, upright and thornless and are resistant to American gooseberry mildew, blackcurrant leaf spot and blackcurrant gall mite. The flowers, which can go unnoticed, are self pollinating and unless protected, are easily damaged by severe frosts in spring. The yield is heavy. I hope this helps.
